Methods

abs() → Number: Returns the absolute value of this Number.
override
ceil() → Number: Returns the least Number having integer components no smaller than this Number.
override
clamp(dynamic lowerLimit, dynamic upperLimit) → Number: Returns this num clamped to be in the range lowerLimit-upperLimit. The comparison is done using compareTo and therefore takes -0.0 into account. This also implies that double.NAN is treated as the maximal double value. lowerLimit and upperLimit are expected to be num or `Number' objects.
inherited
compareTo(dynamic n2) → int: Compares this Number to another Number by comparing values. n2 is expected to be a num or Number. If it is not it will be considered to have a value of 0.
inherited
floor() → Number: Returns the greatest Number with an integer value no greater than this Number. If this is not finite (NaN or infinity), throws an UnsupportedError.
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
reciprocal() → Number: Returns the Number that is the reciprocal of this Number. This Number is unaffected.
override
remainder(dynamic divisor) → Number: Returns the remainder of the truncating division of this Number by divisor. The result r of this operation satisfies: this == (this ~/ other) * other + r. As a consequence the remainder r has the same sign as the operator /(divisor).
override
round() → Number: Returns the integer Number closest to this Number. Rounds away from zero when there is no closest integer: (3.5).round() == 4 and (-3.5).round() == -4. If this is not finite (NaN or infinity), throws an UnsupportedError.
override
toDecimal() → Decimal: Converts this Number to a Decimal. Throws a StateError if the Number has an imaginary or complex component.
inherited
toDouble() → double: Converts this Number to a dart:core double.
override
toInt() → int: Converts this Number to a dart:core int.
override
toJson() → Map<String, dynamic>: Subclasses must support dart:json for stringify.
inherited
toString() → String: A string representation of this object.
override
truncate() → Number: Returns a truncated value.
override

Operators

operator %(dynamic divisor) → Number: The modulo operator. Imaginary and Complex divisors are nor supported and will throw an Exception.
override
operator *(dynamic multiplicand) → Number: Returns the product of this Number and the multiplicand (a Number or num). This Number is unaffected.
override
operator +(dynamic addend) → Number: Addition operator.
override
operator -(dynamic subtrahend) → Number: Returns the difference of this Number and the subtrahend (a Number or num). This Number is unaffected.
override
operator /(dynamic divisor) → Number: Returns the quotient of this Number divided by the divisor (a Number or num). This Number is unaffected.
override
operator <(dynamic obj) → bool: Returns whether the value of this Number is less than the value of obj (a Number or num).
override
operator <=(dynamic obj) → bool: Returns whether the value of this Number is less than or equal to the value of obj (a Number or num).
override
operator ==(Object other) → bool: Two Numbers will be equal when the represented values are equal, even if the Number subtypes are different.
inherited
operator >(dynamic obj) → bool: Returns whether the value of this Number is greater than the value of obj (a Number or num).
override
operator >=(dynamic obj) → bool: Returns whether the value of this Number is greater than or equal to the value of obj (a Number or num).
override
operator ^(dynamic exponent) → Number: The power operator (note: NOT bitwise XOR).
override
operator unary-() → Real: Negation operator.
override
operator ~/(dynamic divisor) → Number: The truncating division operator. When dividing by an Imaginary or Complex number, the result will contain an imaginary component. The imaginary component is not truncated; only the real portion of the result is truncated.
